Some media files are not recognised as such (ogm, mkv, mka)

[Phil Housley]

Binary package hint: shared-mime-info

Certain types of media files are not recognised as being media in nautilus; as can be seen when thumbnailing fails and you just get a blank-page icon. Some I've noticed:

Matroska audio, with .mka extension
Matroska video, with .mkv extension
Ogg with video, with .ogm extension

(These are also not covered by ls' coloring scheme, should that be a separate bug, or is it based on the general mime info?)

Thank you for your bug. What version of Ubuntu do you use?

[Phil Housley (undeconstructed)]

Feisty, entirely up to date as of about 2 hours ago (shared-mime-info 0.19-2ubuntu1.)

[Sebastien Bacher (seb128)]

did it use to work before the update?

[Phil Housley (undeconstructed)]

No. I don't think it ever has.

[Sebastien Bacher (seb128)]

Do you have any example you could point? Either attach a small file to the bug page or give an URI where to download one? Do you use totem-gstreamer or totem-xine? Can you play that video with totem (you might lack some codec to play it)?

[Phil Housley (undeconstructed)]

The problem isn't with thumbnailing, but when that is turned off. I'm attaching a composite shot of nautilus (thumbnails turned off), ls and file.

Nautilus recognises the .mkv file as matroska, and will open it with totem which will play it, but it won't show a media file icon. Likewise, file will show the right data, but ls won't apply the correct colour coding.

[Sebastien Bacher (seb128)]

Does it happen only when thumbnailing is not activated? Having an example would still be useful

[Phil Housley (undeconstructed)]

Well, a thumbnail will be drawn over the icon, so you can't tell what it would be...

Attaching a very small matroska audio file to this comment; Nautilus will try to create a thumbnail, and give up when it finds it can't (as there's no video.) It will then display a blank page icon, even though it recognises that it is a media file (well, it knows that totem can play it anyway.)

[Sebastien Bacher (seb128)]

Confirmed, that's an icon theme problem, there is no gnome-mime-application-x-matroska icon

[dobey (dobey)]

I'm guessing this was caused by the MIME types being incorrect. I just downloaded the attached .mka file, and it appears correctly as the audio/x-matroska mime type, and has the audio-x-generic icon from the theme. Sebastien, should we just close this as Invalid now? Or Fix Released?

[Sebastien Bacher (seb128)]

right that seems fixed so closing the bug
